At MIER, we know that great running shorts do more than just look good—they enhance performance, reduce distractions, and keep you comfortable mile after mile.
So how do you choose the best running shorts? While the perfect pair depends on your personal preferences, there are essential features to look out for to help you stay cool, chafe-free, and focused. Here's everything you need to know.
📈 Quick Summary – How to Choose the Best Running Shorts

✔️ Fit: Comfortable, chafe-free with flat seams

❓ What Should You Look for in Running Shorts?
Finding the perfect pair of shorts starts with a few key performance features that enhance comfort and minimize distractions during your run.
1. Breathability
Staying cool during your run is non-negotiable. Opt for shorts made from breathable, moisture-wicking fabrics like polyester or nylon. Features like mesh panels, split hems, or laser-cut perforations promote airflow and heat release.
Our shorts are engineered with premium ventilation zones to keep you cool even on the hottest days.
2. Comfort
Your shorts should feel like a second skin—no pinching, adjusting, or chafing. Look for:
- Flat or minimal seams to reduce friction
- Adjustable waistbands for a secure fit
- Built-in liners that offer soft support without bulk
- Wide waistbands that stay put as you move
Tip: Try lunges or strides to make sure nothing rides up or digs in.
3. What Running Short Length Is Best for You?
Your choice of length depends on your running style, climate, and comfort needs:
- 3" Shorts: Lightweight and built for speed. Ideal for races and hot weather.
- 5" Shorts: A versatile choice that balances coverage and mobility. Great for everyday training.
- 7" or Longer: More sun and trail protection. Great for cooler weather or rugged terrain.
Want both support and airflow? Choose 2-in-1 shorts: a supportive liner with a lightweight outer layer.
4. Fabric Performance
Skip the cotton. Look for technical, quick-drying fabrics that wick moisture from your skin and dry fast. Our shorts feature high-performance recycled polyester blends that retain breathability, shape, and softness wash after wash.
5. Key Features to Consider
The right details can make all the difference:
- Pockets: Secure space for keys, cards, or gels
- Reflective Elements: For visibility in low-light runs
- Liners: Choose built-in or go liner-free
- Waistbands: Adjustable, wide, and non-restrictive
- Lightweight Build: Less weight = more speed and comfort
📅 How to Choose the Right Size Running Shorts
Men's Sizing Tips
Measure around your natural waistline and aim for a secure, non-restrictive fit. Tall runners might prefer longer inseams for more coverage.
Women's Sizing Tips
Measure both waist and hips. Try a few movements (like lunges or squats) to make sure the waistband stays in place and the fabric doesn’t ride up.
Always check the size chart for best results.
🚶 Shorts vs. Tights: Which Should You Choose?
The weather, terrain, and intensity of your run can determine the better option:
Choose Shorts If:
- It’s hot out and you want max ventilation
- You’re racing or doing speed workouts
- You want lightweight, unrestricted movement
Choose Tights If:
- You need warmth or wind protection
- You want to avoid inner-thigh chafing
- You're trail running and want protection from bushes or ticks
- You prefer compression support
Pro Tip: Try 2-in-1 shorts for the best of both worlds.
